I'm having the same issue where the server console cannot connect.
If you use the mofowallet UI, set nxt.allowedBotHosts to * in both FIMK config and NXT config. Click on the green icon to save and restart the client (server).
Yeah! It works! Now I see peers and my server runs. Thanks!
But when I'm trying to start forging I see the same error message "ERROR. Unknown account"
How to solve this?
I'm preparing an update will release 0.4.1 tomorrow, found a bug that caused this.
